Be it known that I, Evnsm'r- W; VARNEY,

a citizen of the United States, residing-at- Newton, in the county 'of Middlesex and State of Massachusetts, have inventedcertain' Improvements in Machines for and Methods of Lasting Shoes, of which the following description, in connection with the accompanying drawings, is a specification, 10 like reference characters on the drawings indicating like parts in the several figures. This invention relates to methods and machines for' use in lasting shoes and more articularlyto methods and machines for l asting shoes in which the upper is-secured v to the bottom of the sole in lasted position by means'of cement,-as, for example, in the manufacture of shoeshaving. fabric uppers,

which shoes are to have rubber outsoles i0 vulcanized to them.

1 In the manufacture of shoes having rubber soles which are subjected to vulcaniza- -;tion, the innersole in accordance with the f usual practice, is ormed of a rubber compound generallyknown as stock. This innersole is -relatively thin and pliable and its-outer surface is rendered tacky by the application of a suitable rubber compound.

e upper of1the shoe, when repared for lastin has the inner face o 'its margin coate with rubber cement'which, when brought-m contact with the tacky surface of t e innersole, adheres firml thereto. Heretoforeshoes of this kind ave been 1 lasted" almost entirelyb hand, the

J liandwork exceedingly laborious and by' reas'omof. the consequent fatigue of the operator uniform results in the course of a; dayswork are diflicult to 'obtain. As a consequence the manufacturer finds in his product's large number. of reject'shoes it. of, if stall, at,

upon the innersole taxes the endurance of. a person of ordinary strength when kept up continuously in the days work.

An object of. this invention is to provide y than is possible by human agency alone.

a machine for doing this work more rapidly and overlayingo the Afeature' of the invention consists in flexible means operating uniformly by frictional drag t2 overwipe the shoe upper upon the shoe bottom. The flexible means ma ooming margin'of. t e u per and lay it against the margin of the s oe bottom against the innersole. Preferably and as herein shown, a plurality of belt runs, arranged in close rovided which act simultaneously upon t eportion of the upper being-treated. j 1 Another feature of the invention consists in novel means for treating the overlaid upper by'impact, for example, by rapidly re ated blows during the overwi ing operatib n; Preferably and as SlIOWIlE erein, the .blows are delivered u n the flexible yields ingmeans through w oh the force'of 'im pact is transmitted to the shoe upper to cause firm adhesion between the upper and the tacky surface of the innersole.

Another feature ofthe' invention consistsin an organization by which the means for delivering blows to beat the up er is given a component of;movement in a 'rection mwardly of the shoe bottom as well as a' component of movement pe dicular to the shoe m. The inw y component is, therefore, in the. samedirection as the movement of the flexible yielding means which wipes the up r over the shoe bottom. Preferably blow -me:.lnasj;; beate which-i 1 e on e y 1 means ismova e ut igfi the flexible yielding means while in mo'mentary contact therewith;

Another feature of. the invention consists in' the "combination with flexible overwiping means, of-means for upwiping the upper the portion ,ofthe" tion'being overwiped by l flexible-means.

The upwipingmeans is preferably flexible and yielding and acts by its frictional drag to upwipe and tension the shoe upper at the side of the shoe toward the last bottom. As herein shown, a plurality of upwiping means in the form of belt runs are provided which act to upwipe and tension the upper at the side of the shoe adjacent to the marginal "portion which is being overwiped by the overwiping means.

Another feature of the invention consists in the combination of a plurality of continuously operating upwiping means and a plurality of continuously operating overwiping means. As shown herein, individual members'of each plurality of wipingmeans are arranged alternately with the individual members of-the other plurality of wiping means; that is, the wiping means are interdigitally arranged. Each set of wiping means may comprise a series of belt runs arranged yieldingly to engage the upper and wipe and tension it in the directionof travel of the belt runs. One series of belt runs is preferably arranged at an angle to the. other series of belt runs, the angle being variable and corresponding approximately to the angle between the side of thelast and the bottom of the last. The beating or impacting means above referred to, which acts upon the overlaying means, may be arranged to act upon all of the overlaying belt runs to force the upper against the shoe bottom, or, if it is desired, may be arranged to act only upon some of thosebelt runs, for example, upon one or more of the belt ru'ns which last treat the upper as the lasting operation progresses about the periphery of the shoe.

Another feature of the invention consists in an organization for effecting a more rapid operation of the overwiping means than of the upwiping means to. secure an increased frictional drag upon the portion of upper which is wiped over the shoe bottom.

Another feature of the invention consists in an organization whereby the direction of movement of the overwiping means relatively to the edge of the shoe may be such as to cause .the 'overwiping to be effected in a direction'inclined toward the toe of the shoe or inclined toward the heel.

J Another featureof theinvention consists in anorganization of the machine wherebyv the direction of movement of the upwiping means relatively to the shoe bottom may be varied to causethe upwiping to be effected upwardly and toward the toe of the shoe or upwardly and toward the rear of the shoe to secure the stretching of the upper in the direction of the sole edge or to gather the upper for disposing of excessive fullness I thereof, As shown herein, a change inthe action of the overwiping means may be effec'ted with or without a changein the position of the plane-0f action of the series of upwiping belts. Conversely, a change in the direction of action of the upwiping means may be effected with or without a change in the position of the plane of action of the series of overwiping belt runs.

The novel method practiced in the use of the machine consists in upwiping a portion of a shoe upper, then overwiping the upwiped portion, and beating down the overwiped portion into engagement with the innersole. The upwiping may be continued durlng the overwiplng and beating which preferably are performed simultaneously.

referably the upwiping is effected along a plurality of closely adjacent lines and the over-wiping along lines located between the lines of upwiping. Thebeating preferably comprises the application of an ifnpactive force through a yielding medium which may conveniently be the overwiping means, said means preferably comprising elastic belts of friction material such as rubber, to the outer faces of which the impactive force is intermittently applied to cause the areas of contact of the belts to be extended laterally.

The method further consists inupwiping the upper along a plurality of lines at an angle to the plane of the shoe bottom to tension the upper longitudinally as well as transversely of the last, and in overwiping the upper along a plurality of lines at an angle to the edge of the last to produce partly in section;

and

Figs. 5, 6 and al' Views, diagrammatic in character; illustrating methods of last-'- ingaccording to my invention.

Referr ng first 1; Figs. 1 and 2., the frame of the machine comprises. a standard 12 having a rearwardly extending arm 13' and .a front yoke-shaped arm 14;

Mounted in suitable bearings is a. shaft 15 having a worm wheel 16 driven by a worm 17 carried by a shaft'18 actuated byany suitable power, preferably an electric motor.

. Carried by the-shaft 15' are pulleys '19 by I means of which the single continuous beltis driven, as hereinafter described. Sup- '27 between the bearing 26- and the lock '24 serves yieldingly to maintain the block 24,'its stem and the pulleys 23, outward,

to keep the belt 33 under tension and to compensate for stretching of the belts. ,A shaft 28 car ing a series of idle ulleys 29 is mounte in a yoke 30 depen g from and secured to a cross-web 31 of the frame. A single idle pulley 32 is mounted on a stud shaft suitably supported by-the frame near the lower end thereof and'preferably vat an angle such as illustrated in Figs. 1 and 2.

A single endless belt 33 of friction material and suitably of elastic material such as rubber, is mounted so as to run progressively over all of the pulleys hereinbefore ,de-

scribed, the course ofv such. belt being most clearly illustrated ,in Fig. The direction of the belt is such that a plurality of runs of the belt move in a substantially-vertical direction and another plurality of runs of the 'belt extend in a substantially horizontal direction, so that the vertically moving runs of .the belt operate to wipe the upper of a shoeup the side of a lastand a the horizontal runs of the belt operate to wipe the marginal portion ofthe upper over and against the shoe bottom as illustrated in Figs.- 2, 5-and 6.

Owing to the fact that the belt runs are all substantially'equally elastic and are capable of being flexed more or less according to the degree of ressure. brou ht to bear against them by t e operator w 'en moving the shoe along, the lasting action of the belt runs can be varied considerably and effected continuously and progressively along the shoe.

5 byffull lines in 7 and is moved along" 1 ;Normally the. vertical runs -of the belt are in the relative positions shown in Fig.

6. The last and the shoe parts thereon may be manipulated bythe operator, while mov- 4 ing the shoe along so that the belt runs toward one edge 0 the series will be flexed more than the belt mm at the other edge of 'the series, this depending-upon the angle of (presentationof the work to the beltruns an the amount of pressure against said either upward against the horizontal runs or,la terally against the vertical runs. If thesho'e' is held in the position indicated =1 past the belt runs in the direction of the ar- 7 X insaidfigure, the vertical belt 33 will actwithgraduallyincreasing pressure. "l his is because the vertical belt run ried by an arm 36 of a lever?) 33 at the left is flexed more than the one at the right of the series. The same is true as to the horizontal belt runs.v Thatis, by tilting the shoe 'endwise, the-horizontal belt runs maybe caused successively to act with increasin step-by-step pressure. 7

The ful and dotted-line representations of difierent positions of the shoe indicated.

In order more'firmly to secure the cemented portions of the margin of the upper to the shoe bottom, -I employ a. beating mechanism to act upon the horizontal runs of the belt. The mechanism for doing this,

as illustrated in Figs. 1 and 2, comprises a series of rolls 34 mounted upon a in 35 car- I which is pivotally connected at 38 to the bearing member '26. The other end of the lever 37 extends 'into the path of operation of a tappet cam39 carried by the shaft 15, a spring 40 being connected at one end to the lever 37 and at the other end to any suitable sup- 7 port. The relative proportions of the parts of this mechanism are'such that as the shaft 15 revolves the tappet cam acts upon the lever 37 to lift it while the spring 40, as soon as each cam rise leaves the end of the lever 37, pulls the-lever down and causes "margin can not be moved into contact with thefhorizont'al stretches of the belt.

.I do not limit myself to the'employmen't of a single belt following a course to present a plurality of parallel runs. As indi- 119 cated in 'Fig. 4, a series of beltsi33' may be. mounted u'pon' the'up 1' and lower pulleys- I9, 29 and" another SGIIGS Of belts 33 may be mounted upon pulleys 23 and 21, and also over a third of pulleys ,45 secured to a drivenshaft 46: With such a structure I am able to drive the pulleys" 45 at a pcriphera-l speed different from that of the pulleys 19, such difference of speed being A to cause the runs 33 to travel at a higher 120 by dotted circles in Fig.4. Since the shaft 15 is positively driven, as hereinbefore described in connection with Fig. 2, the gear connections between shafts 15, 46 provide 4 for driving the pulleys 45 so as to impart a" higher speed to the belt runs 33"- than the 1 v speed of the belt runs 33". lVith this structure the shoe may be so manipulated that while'the vertical belt runs Wlll operate to wipe the upper on the sides of the last to ward the shoe bottom, that wiping action is somewhat increased by the action of the horizontal belt runs.

A preferred method of lasting shoes by means of my machine is to grasp the shoe in the hands and present a portion of the side of the shoe first tothe vertical belt runs 33 the upwiped portion is engaged by the horizontal runs \33 and overwiped uponthe shoe bottom, Upward pressure on the shoe during the overwiping brings the boaters into action and impactive' force is applied to the overlaid-upper through the yielding media afforded by the flexible overwiping belts. If the belts are of rubber the impactive force causes the belts to be flattened to extend the lines of contact laterally from the lines of first engagement.

I do not limit myself to the employment of boaters such as 'hereinbefore' described. It a machine of this character is to be employed for lasting leather shoes, which require tacks for securing the margin of the upper, I may employ suitabletack driving mechanism with a nozzle located as indicated at 48 in Fig. 4, said mechanism being adapted to drive tacks through the margin of the uper the nozzle 48 bein of course located .to direct the tacks between two of the belt runs 33 For this purpose a tacking mechanism having a tripping nozzle mayconveniently be employed such, for example, as that disclosedin United States Letters Patent No. 1,188,618,.granted June 27, 1916, on.

application of-Matthias Brock. lVith such an organization as shown in Fig. 4 the oporator may cause a tackto be driven through the'o\ 'erlaid upper by raising the shoe against the horizontal runs 33 and lifting them sufiicientlyto enable the shoe to engage and trip the nozzle 48 of the tacker;

llaving thus described my invention, what I claim; as new and desire to secure .by Letters Patent of the United States'i-s:
